Two gardai were recovering from gunshot wounds after responding to reports of shooting in Blanchardstown last Tuesday evening.
They responded to shots being fired from a house Whitechapel Grove where they were forced to take cover behind a garda car which was hit by several bullets.
The gardai were both hit in the foot while one also suffered a hand wound.
The stand off led to the area being shutdown for hours with local football training among other things affected whiile residents nearby were also evacuated from their homes.
It took hours of coaxing by trained negotiators before the man surrendered. Gardai recovered two firearms, a pistol and a machine machine from the house.
A man in his 40s was immediately arrested and is known for previous involvement in organised crime.
The injured gardaí were transferred to Connolly Hospital Blanchardstown for treatment. They were commended by the Taoiseach Micheál Martin for their bravery and he wishes them both a speedy recovery.
The Garda Commissioner Drew Harris added his voice to the praise for the two officers who were first on scene.
